Authorization failed because the token is missing required OAuth scopes.
Unlike a bare ``AuthorizationError``, this carries the specific scopes the
caller must obtain. A component-level scope shortfall can then be signalled
as a spec-correct ``insufficient_scope`` step-up (SEP-2350 / RFC 6750 §3),
naming exactly what to re-authorize for instead of an opaque denial. The
named scopes are only the *unmet* ones, so an existing grant is accumulated
rather than replaced when the caller re-authorizes.
